Antenna Ports OUT

The EU has two duplex 4.3-10 female antenna ports for transmitting and

receiving signals to and from distributed antennas. These RF ports can be connected

directly to antennas (i.e. using RF jumper cables) or through splitters, allowing

additional antennas to be fed by the EU.

Antenna Ports IN

The EU has two duplex 4.3-10 female antenna ports for connecting the

antenna OUT ports of two ION-U L 7/80-85/17P/19P. The signals are combined and

fed to the RF antenna OUT ports of the EU.
